Date: Fri, 07 Mar 2014 18:47:30 +0800 From: Gu Zheng <guz.fnst@...fujitsu.com> To: "David S. Miller" <davem@...emloft.net> CC: netdev@...r.kernel.org, linux-kernel <linux-kernel@...r.kernel.org> Subject: [PATCH] netlink: switch net_ns only if net is not init_net Many netlink users create netlink sock in the init_net, and the switching nes_ns(init_net-->net) is needless in this case. So here we add a pre-check to avoid this.
